KyberSwap Arbitrage

Perform triangular arbitrage on Base via KyberSwap by finding profitable token swaps, calculating optimal paths, and executing multi-hop trades with gas and...

Overview

Triangular arbitrage: profit from price differences between 3 tokens (e.g., USDC → ETH → USDT → USDC)

Key Contracts (Base Mainnet)

• Router: 0x6131B5fae19EA4f9D964eAc0408E4408b2a37dD8
• Factory: 0x5F1dddbf348aC2BEbe18559BF0eDE9D3fE6ce35f

Core Logic

1. Get Quotes

const router = new ethers.Contract(routerAddr, routerABI, provider);

// Get amounts out for exact input
const [amountOut] = await router.getAmountsOut(
  amountIn,      // Wei amount
  [tokenA, tokenB, tokenC] // Path
);

2. Calculate Profit

profit = finalAmount - initialAmount - gasCosts

3. Execute Swap

const tx = await router.swapExactTokensForTokens(
  amountIn,
  amountOutMin,
  path,
  recipient,
  deadline
);

Token Addresses (Base)

• USDC: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
• USDT: 0xfde4C96c85940E8F44A6D8d5e4fD4f4C4f9D8E8
• ETH: 0x4200000000000000000000000000000000000006
• WETH: 0x4200000000000000000000000000000000000006

Arbitrage Pairs (Base)

Common triangular paths:

• USDC → ETH → USDC
• USDC → WETH → USDT → USDC
• USDT → ETH → USDC → USDT

Safety Checks

1. Slippage: Set amountOutMin = output * (1 - slippage%)
2. Gas: Estimate gas, ensure profit > gas
3. Max Price Impact: Check pool reserves before large trades
4. Renounced Contracts: Only trade tokens with renounced ownership

Risk Profile

• Aggressive but audit-first
• Skip all non-renounced contracts
• Check for honeypot tokens
